PrepU Questions: Oxygenation Exam 2

A nurse caring for a client with deep vein thrombosis must be especially alert for complications such as pulmonary embolism. Which findings suggest pulmonary embolism?

Chest pain and dyspnea As an embolus occludes a pulmonary artery, it blocks the supply of oxygenated blood to the heart, causing chest pain. It also blocks blood flow to the lungs, causing dyspnea. The client with pulmonary embolism typically has a cough that produces blood-tinged sputum (rather than a nonproductive cough) and chest pain (rather than abdominal pain). Hypertension, absence of fever, bradypnea, and bradycardia aren't associated with pulmonary embolism.

A client has undergone a left hemicolectomy for bowel cancer. Which activities prevent the occurrence of postoperative pneumonia in this client?

Coughing, breathing deeply, frequent repositioning, and using an incentive spirometer Activities that help to prevent the occurrence of postoperative pneumonia are: coughing, breathing deeply, frequent repositioning, medicating the client for pain, and using an incentive spirometer. Limiting fluids and lying still will increase the risk of pneumonia.

The nurse is working on a busy respiratory unit. In caring for a variety of clients, the nurse must be knowledgeable of diagnostic studies. With which diagnostic studies would the nurse screen the client for an allergy to iodine? Select all that apply

Lung scan Fluoroscopy Pulmonary angiography The nurse must be well educated in screening clients before diagnostic procedures which include contrast medium for an allergy to iodine. A lung scan, fluoroscopy and pulmonary angiography all require contrast medium.

A patient visited a health care clinic for treatment of upper respiratory tract congestion, fatigue, and sputum production that was rust-colored. Which of the following diagnoses is likely based on this history and inspection of the sputum?

an infection with pneumococcal pneumonia Sputum that is rust colored suggests infection with pneumococcal pneumonia. Bronchiectasis and a lung abscess usually are associated with purulent thick and yellow-green sputum. Bronchitis usually yields a small amount of purulent sputum.

Which of the following clinical manifestations should a nurse monitor for during a pulmonary angiography, which indicates an allergic reaction to the contrast medium?

difficulty in breathing Nurses must determine if the client has any allergies, particularly to iodine, shellfish, or contrast dye. During the procedure, the nurse should check for signs and symptoms of allergic reactions to the contrast medium, such as itching, hives, or difficulty in breathing. The nurses inspects for hematoma, absent distal pulses, after the procedure. When the contrast medium is infused, an urge to cough is often a sensation experienced by the client.

A client hospitalized with pneumonia has thick, tenacious secretions. Which intervention should the nurse include when planning this client's care?

encouraging increased fluid intake Increasing the client's intake of oral or I.V. fluids helps liquefy thick, tenacious secretions, and ensures adequate hydration. Turning the client every 2 hours would help prevent atelectasis, but will not adequately mobilize thick secretions. Elevating the head of the bed would reduce pressure on the diaphragm and ease breathing, but wouldn't help the client with secretions. Maintaining a cool room temperature wouldn't help the client with secretions.

A nurse is caring for a client who was admitted with pneumonia, has a history of falls, and has skin lesions resulting from scratching. The priority nursing diagnosis for this client should be:

ineffective airway clearance

Which term is used to describe the inability to breathe easily except in an upright position?

orthopnea Clients with orthopnea are placed in a high Fowler's position to facilitate breathing. Dyspnea refers to labored breathing or shortness of breath. Hemoptysis refers to expectoration of blood from the respiratory tract. Hypoxemia refers to low oxygen levels in the blood.

When interpreting the results of a Mantoux test, the nurse explains to the client that a reaction occurs when the intradermal injection site shows

redness and induration The injection site is inspected for redness and palpated for hardening. Drainage at the injection site does not indicate a reaction to the tubercle bacillus. Sloughing of tissue at the injection site does not indicate a reaction to the tubercle bacillus. Bruising of tissue at the site may occur from the injection but does not indicate a reaction to the tubercle bacillus.

The nurse assesses a patient for a possible pulmonary embolism. What frequent sign of pulmonary embolus does the nurse anticipate finding on assessment?

tachypnea Symptoms of PE depend on the size of the thrombus and the area of the pulmonary artery occluded by the thrombus; they may be nonspecific. Dyspnea is the most frequent symptom; the duration and intensity of the dyspnea depend on the extent of embolization. Chest pain is common and is usually sudden and pleuritic in origin. It may be substernal and may mimic angina pectoris or a myocardial infarction. Other symptoms include anxiety, fever, tachycardia, apprehension, cough, diaphoresis, hemoptysis, and syncope. The most frequent sign is tachypnea (very rapid respiratory rate).

Which would be least likely to contribute to a case of hospital-acquired pneumonia?

A nurse washes her hands before beginning client care. HAP occurs when at least one of three conditions exists: host defenses are impaired, inoculums of organisms reach the lower respiratory tract and overwhelm the host's defenses, or a highly virulent organism is present.

A patient comes to the clinic with fever, cough, and chest discomfort. The nurse auscultates crackles in the left lower base of the lung and suspects that the patient may have pneumonia. What does the nurse know is the most common organism that causes community-acquired pneumonia?

Streptococcus pneumoniae

A 44-year-old homeless man presented to the emergency department with hemoptysis. The patient was diagnosed with tuberculosis (TB) after diagnostic testing and has just begun treatment with INH, pyrazinamide, and rifampin (Rifater). When providing patient education, what should the nurse emphasize?

The importance of adhering to the prescribed treatment regimen Successful treatment of TB is wholly dependent on the patient's conscientious adherence to treatment. Patient education relating to this fact is a priority over MDIs, incentive spirometry, or nutrition, although each may be necessary.

The nurse caring for a client with tuberculosis anticipates administering which vitamin with isoniazid (INH) to prevent INH-associated peripheral neuropathy?

Vitamin B6 Vitamin B6 (pyridoxine) is usually administered with INH to prevent INH-associated peripheral neuropathy.

A client is admitted to the facility with a productive cough, night sweats, and a fever. Which action is most important in the initial care plan?

placing the client in respiratory isolation Because the client's signs and symptoms suggest a respiratory infection (possibly tuberculosis), respiratory isolation is indicated. Every 8 hours isn't frequent enough to assess the temperature of a client with a fever. Monitoring fluid intake and output may be required, but the client should first be placed in isolation. The nurse should wear gloves only for contact with mucous membranes, broken skin, blood, and other body fluids and substances.

A nurse assesses a client's respiratory status. Which observation indicates that the client is having difficulty breathing?

use of accessory muscles

A nurse is caring for a client who is at high risk for developing pneumonia. Which intervention should the nurse include on the client's care plan?

using strict hand hygiene The nurse should use strict hand hygiene to help minimize the client's exposure to infection, which could lead to pneumonia. The head of the bed should be kept at a minimum of 30 degrees. The client should be turned and repositioned at least every 2 hours to help promote secretion drainage. Oral hygiene should be performed every 4 hours to help decrease the number of organisms in the client's mouth that could lead to pneumonia.

A nurse is administering a purified protein derivative (PPD) test to a client. Which statement concerning PPD testing is true?

A positive reaction indicates that the client has been exposed to the disease A positive reaction means the client has been exposed to TB; it isn't conclusive for the presence of active disease. A positive reaction consists of palpable swelling and induration of 5 to 15 mm. It can be read 48 to 72 hours after the injection. In clients with positive reactions, further studies are usually done to rule out active disease. In immunosuppressed clients, a negative reaction doesn't exclude the presence of active disease.

A recent immigrant is diagnosed with pulmonary tuberculosis (TB). Which intervention is the most important for the nurse to implement with this client?

Developing a list of people with whom the client has had contact

A client has a nursing diagnosis of "ineffective airway clearance" as a result of excessive secretions. An appropriate outcome for this client would be which of the following?

lungs are clear on auscultation Assessment of lung sounds includes auscultation for airflow through the bronchial tree. The nurse evaluates for fluid or solid obstruction in the lung. When airflow is decreased, as with fluid or secretions, adventitious sounds may be auscultated. Often crackles are heard with fluid in the airways.

Which statement indicates a client understands teaching about the purified protein derivative (PPD) test for tuberculosis?

"Because I had a previous reaction to the test, this time I need to get a chest X-ray." A client who previously had a positive PPD test (a reaction to the antigen) can't receive a repeat PPD test and must have a chest X-ray done instead. The test should be read 48 to 72 hours after administration. Redness at the test area doesn't indicate a positive test; an induration of greater than 10 mm indicates a positive test. The client doesn't need to avoid contact with people during the test period.

A client at risk for pneumonia has been ordered an influenza vaccine. Which statement from the nurse best explains the rationale for this vaccine?

"Viruses like influenza are the most common cause of pneumonia." Influenza type A is the most common cause of pneumonia. Therefore, preventing influenza lowers the risk of pneumonia. Viral URIs can make the client more susceptible to secondary infections, but getting the flu is not a preventable action. Bacterial pneumonia is a typical pneumonia and cannot be prevented with a vaccine that is used to prevent a viral infection. Influenza is not the major cause of death in the United States. Combined influenza with pneumonia is the major cause of death in the United States.

The nurse is educating a patient who will be started on an antituberculosis medication regimen. The patient asks the nurse, "How long will I have to be on these medications?" What should the nurse tell the patient?

6 to 12 months Pulmonary tuberculosis (TB) is treated primarily with anti-TB agents for 6 to 12 months. A prolonged treatment duration is necessary to ensure eradication of the organisms and to prevent relapse.

The nurse is caring for a client diagnosed with pneumonia. The nurse assesses the client for tactile fremitus by completing which action?

Asking the client to repeat "ninety-nine" as the nurse's hands move down the client's thorax While the nurse is assessing for tactile fremitus, the client is asked to repeat "ninety-nine" or "one, two, three," or "eee, eee, eee" as the nurse's hands move down the client's thorax. Vibrations are detected with the palmar surfaces of the fingers and hands, or the ulnar aspect of the extended hands, on the thorax. The hand(s) are moved in sequence down the thorax, and corresponding areas of the thorax are compared. Asking the client to say "one, two, three" while auscultating the lungs is not the proper technique to assess for tactile fremitus. The nurse assesses for anterior respiratory excursion by placing the thumbs along the costal margin of the chest wall and instructing the client to inhale deeply. The nurse assesses for diaphragmatic excursion by instructing the client to take a deep breath and hold it while the diaphragm is percussed.

The nurse is planning the care for a client at risk of developing pulmonary embolism. What nursing interventions should be included in the care plan? Select all that apply.

Encouraging a liberal fluid intake Instructing the client to move the legs in a "pumping" exercise Using elastic stockings, especially when decreased mobility would promote venous stasis Applying a sequential compression device The use of anti-embolism stockings or intermittent pneumatic leg compression devices reduces venous stasis. These measures compress the superficial veins and increase the velocity of blood in the deep veins by redirecting the blood through the deep veins. Having the client move the legs in a "pumping" exercise helps increase venous flow. Legs should not be dangled or feet placed in a dependent position while the client sits on the edge of the bed; instead, feet should rest on the floor or on a chair.
